A geological history of Minnesota which includes a discussion of the state's mineral resources and a guide to the geological sites.
Have you ever wondered how the Mississippi River was formed? Or why shark teeth have been found in the Iron Range of the Upper Midwest? Towering mountain ranges, explosive volcanoes, expansive glaciers, and long-extinct forms of both land and sea life were important parts of Minnesota's ancient history. Today the evidence of this remarkable heritage is revealed in the state's rocky outcroppings, stony soils, and thousands of lakes.
Minnesota's Geology provides a history of the past 3.5 billion years in the area's development. In accessible language, Minnesota-based geologists Richard W. Ojakangas and Charles L. Matsch tell the story of the state's past and offer a guide for those who want to read geological history firsthand from the rocks and landscapes of today.
The book's four sections give a short introduction to geology and Minnesota's place in geologic history; a historic timeline; a look at the metallic minerals, nonmetals, and water present today; and a geologic picture of today's Minnesota arranged in five geographical regions. Lavishly illustrated with color and black-and-white photographs, as well as extensive graphs and maps, Minnesota's Geology will inform and delight for years to come.
